Show transcribed image textFor the network below, the switch has been at position b for a long time. At t = 0, periodic switching at a 100 times per second. Let Vg = 9 VDC, C = 1 mu F. Design values for R1 and R such that The capacitor is fully charged during the charging cycle The capacitor only falls down 30% of its maximum value during the discharging time Determine Vca(t) = Voltage across the capacitor at position a Vcb(t) = Voltage across the capacitor at position b The value or R1 and R to satisfy the design requirement Hint use x(t) = xf + (xo - xf)e-(t - to)/T to find quick solution
